Five- and six-membered I±-trimethylsilyl-I±,I²-unsaturated cycloalkenones were prepared by the Wurtz-Fittig coupling reaction of the corresponding 6-bromo-1,4-dioxaspiro4,ncycloalk-6-enes with sodium and chlorotrimethylsilane. Upon treatment with anhydrous AlCl3, the compounds underwent carbon-silicon bond scission to yield a novel class of compounds: the 2-(hydroxydimethylsilyl)cycloalk-2-enones.
五元和六元 I±-trimethylsilyl-I±,I²-不饱和环烯酮是通过相应的 6-bromo-1,4-dioxaspiro4,ncycloalk-6-enes 与钠和氯三甲基硅烷的 Wurtz-Fittig 偶联反应制备的。用无水 AlCl3 处理后,这些化合物发生碳-硅键断裂,产生一类新的化合物:2-(羟基二甲基甲硅烷基)环烷-2-烯酮。© ARKAT-USA, Inc.
